NE5532AD8R2 - Dual 10MHz Low-Noise Op Amp | onsemi
料号： NE5532AD8R2 ✓ 量产中NE5532AD8R2 概述
An operational amplifier is an analog signal-processing IC that compares its inverting and non-inverting inputs and drives its output to amplify the difference between them. The NE5532 belongs to the internally compensated operational-amplifier family within the broader amplifier, analog IC, and semiconductor hierarchies. Internal compensation makes the amplifier stable without an external compensation network, simplifying conventional audio and instrumentation designs. Its dual-channel configuration reduces component count and board area when two gain stages are required.
The NE5532AD8R2 is specifically described as a low-noise dual amplifier. Its 10 MHz gain-bandwidth product supports audio-frequency amplification and general closed-loop signal conditioning, while the 70 dB common-mode rejection helps reject common-mode disturbance on differential inputs. The low 200 nA input bias current can simplify biasing of higher-impedance source networks, although the supplied data does not establish input impedance, input capacitance, slew rate, or output-current capability.
Typical uses include stereo audio preamplification, active equalization, low-level microphone-stage amplification, instrumentation buffering, and dual-channel analog filtering. In a preamplifier, the device can be configured as a non-inverting stage with feedback resistors, while the two internal channels can process left and right signal paths independently. In instrumentation circuits, the dual format can support gain and active filtering functions without requiring two separate amplifier packages.
Designers should preserve the SOIC-8 footprint and verify the exact channel pin assignments against the manufacturer datasheet before layout release. Decoupling capacitors should be placed close to the supply pins, and unused amplifier channels require appropriate input termination rather than being left floating. Input and output swings, gain-bandwidth behavior, stability, and output-current limits must be checked against the circuit operating conditions.
This page consolidates the verified onsemi and distributor information, provides package-level selection guidance, and distinguishes electrically similar candidates from confirmed drop-in replacements. Pricing, lifecycle classification, exact pin names, and several detailed electrical parameters remain explicitly marked where the supplied source data does not provide authoritative values.

典型应用
NE5532AD8R2 适用于 6 应用s: Stereo Audio Preamplifier, Active Equalizer and Tone Control, Low-Level Instrumentation Amplification, Active Audio Filters, Audio ADC Input Conditioning, Sensor Signal Buffering.
Stereo Audio Preamplifier
The NE5532AD8R2 fits stereo preamplification because its dual-channel 8-SOIC package can process left and right signals independently. Its 10 MHz gain-bandwidth product is ample for many audio-band gain stages, while the 70 dB common-mode rejection ratio helps limit interference coupled equally into both inputs. Each channel can use a conventional inverting or non-inverting feedback network. The design must still verify output swing, load capability, and stable gain against the manufacturer electrical limits, because the supplied data does not establish maximum output voltage or drive current.
推荐
Active Equalizer and Tone Control
NE5532AD8R2 is suitable for active equalization because it provides two channels for linked or independent frequency-shaping networks. The 10 MHz gain-bandwidth product supports closed-loop gains commonly used around the audio band, while 200 nA input bias current can simplify the interaction with source impedances. One channel may implement a bass network and the other a treble or general-purpose filter. Because the supplied information does not specify noise density, slew rate, or maximum output swing, those values should be checked before using very low cutoffs, high boost, or large source impedances.
推荐
Low-Level Instrumentation Amplification
The NE5532AD8R2 can amplify low-level instrumentation signals where moderate bandwidth, low input bias current, and common-mode rejection are useful. Its 200 nA bias current and 70 dB CMRR can help preserve small differential signals, and the two channels can implement gain and filtering stages in one package. The 10 MHz gain-bandwidth product permits higher closed-loop gains than its audio-focused application might imply. Before adoption, engineers should verify input offset voltage, input voltage noise density, input common-mode range, output swing, and precision drift because these parameters were not included in the supplied source excerpts.
推荐
Active Audio Filters
NE5532AD8R2 can implement active low-pass, high-pass, or band-pass stages because it combines a 10 MHz gain-bandwidth product with two channels in an 8-pin SOIC. Using the channels for cascaded or parallel filter sections can provide a compact implementation of a stereo crossover, rumble filter, or anti-alias network. The dual topology reduces package count while permitting independent component values. Stability and frequency response depend on the selected noise gain, feedback topology, and source impedance, so the manufacturer stability guidance and exact output-swing limits should be checked against the intended filter response.
推荐
Audio ADC Input Conditioning
NE5532AD8R2 can provide gain and filtering ahead of an audio converter when the source requires a low-noise, moderate-bandwidth amplifier. The 70 dB common-mode rejection ratio can reduce common-mode pickup in balanced or semi-balanced paths, while the 10 MHz bandwidth provides margin above the audio band. The dual arrangement can condition two channels symmetrically before conversion. Input bias current of 200 nA is relevant when working with high-impedance transducers, but source impedance must remain within the amplifier’s input and stability limits, and the ADC’s full-scale range must be respected through appropriate gain selection.
推荐
Sensor Signal Buffering
The NE5532AD8R2 can buffer sensor outputs when the signal bandwidth is well below 10 MHz and the application benefits from low input bias current and a ±3 V to ±20 V supply capability. Its two channels allow simultaneous handling of two sensor signals or use in a gain-and-buffer arrangement. The 200 nA input bias current can minimize loading effects on resistive sensors, although sensor output impedance and amplifier input capacitance still determine usable bandwidth. Verify the input common-mode range, input offset voltage, and output-drive requirements because the supplied verified excerpts do not quantify them.

设计说明
Place the supply bypass capacitor directly between the appropriate supply pin and ground, with the shortest possible trace loop. For an 8-SOIC, avoid routing sensitive input traces beneath or immediately beside the clock-like supply entry and return paths. Keep the two SOIC leads as short as practical, use a continuous ground reference, and place input and feedback components close enough to minimize parasitic coupling. The supplied material identifies an 8-SOIC package but does not reproduce the pin drawing, so confirm every physical connection against the current manufacturer datasheet before fabrication.
Do not treat a same-package candidate as an automatic drop-in replacement. Confirm the pin map, offset-null configuration, supply pins, input common-mode range, output swing, gain-bandwidth product, slew rate, and stable feedback configuration. NE5532AD8R2 is verified at 10 MHz gain-bandwidth product, 200 nA input bias current, 70 dB CMRR, and ±3 V to ±20 V supply operation. Those values should be compared with the actual circuit requirements; package equivalence alone is not sufficient for production substitution.
Choose the closed-loop gain and feedback resistor values so the required signal bandwidth remains comfortably below the 10 MHz gain-bandwidth product and the circuit remains stable with the source impedance. This is especially important for high-Q active filters, where component tolerances and parasitic capacitance can shift poles. Use resistor networks with suitable noise and thermal performance, and avoid excessively large feedback resistors with the 200 nA input bias current. Where a sensor drives the input, account for bias-current error across its source resistance before setting the signal gain.
Budget the dual amplifier’s supply consumption from the verified 38 mA per channel rating, corresponding to 76 mA for two active channels under the cited condition. Actual consumption can vary with supply voltage, load, and operating state, so confirm the datasheet test conditions and worst-case application load. Check output-current demand separately because supply current is not a substitute for output-drive capability. If the design can remain inactive during part of its operating cycle, a power-gating or shutdown strategy may reduce consumption, but only if the amplifier state is properly controlled.
合规信息
The supplied verified excerpts contain no explicit compliance declarations. The tape-and-reel packaging reference points to onsemi document BRD8011/D, but no compliance conclusion was inferred from that reference. AEC-Q100 status is unknown because the excerpts do not identify an automotive-qualified ordering variant.
